Well, I have used VS in a professional environment (working at a semi-large software house). Part of the point I was trying to make is that VS is not just great as an IDE, it is also great as an editor, and that these particular features do not exist in any UNIX/MacOS I have come across.
Your claim that most of the things exist in virtually every editor is simply not true --- many editors have many features, but none have all the features AND work well (fast, stable, etc.). E.g. Eclipse has most of the features, but I find it rather sluggish.
Saying things like "I am almost positive ... you've never opened VS before" is a personal attack, childish and not true.
"I'm positive you've never open VS before" isn't a personal attack, "I'm positive you're ignorant and ugly because I dislike your opinions" is a personal attack. I have no troubles with Eclipse, but I don't use it for big projects so maybe it does get slow. Nonetheless, the features you listed (tabs, searching, project browser and refactoring) are in every halfway decent text editor; I think Notepad++ has most or all of those.
Also, you're adopted and your parents don't really love you
